' WITNESSES Arrow/5Y3 I rocating member maybe provided with pro jections H on opposite sides of the shaft B,

as shown, and 'in this case the toothed rings 7 and pinions G Imght be dispensed with, and the guides on the disks need not be formed as 'grooves. The provision of the rings and pinions 1s however of greater im- I portance when projections H are provided only on one side'of the shaft,-as they must I or preferably, as shown, elastically, the piston rod I being chambered to receive-a spring J and also theend stem H ofthe reciprocating member H, a pin H? which,

works in slots 1 serving to prevent thepiston fromturning relatively to the reciprocating members or separating from it. The

piston works within a cylinder K secured to the casing A. The lower or inner chamber of the cylinder preferably is closed and has an air inlet controlled by a check valve L opening into the cylinder, and a lift-lever may be provided to manually open the vialve L. when desired. From the same c1 amber of the cylinder K a passage K controlled by a check valve N, leads to the upper 01' working chamber ofthe cylinder,

said passage being connected withacarbureter' between the valve N and the working chamber, or containing a carbureter. The particular constructionshown, to which I d6 not limit myself, comprises a fuel supply pipe 0, the outlet of which is closed by a valve P when air rushes upwardthrough the passage K.. When the valve'P is open, the i (gasolene) flows and collects on periioratedpartitions K K K* the lower one 6f which has aseat for the valve P seas to close the. perforation of said partition -when the valve P is down.

Q is a pipe vleading to the fuel tank g so as to createpressure therein to feed the fuel through the pipe 0, and Q is a pipe lead- "lng to a tank for storing air under pres-' sure, forthe purpose. of more readily starting the engine, by using the starting con- "'nection Q normally closed by a cock Q".

Q is a drip cock, and-Q a relief cock, .Whether I employ the particular constrfxqtlon of carbureter above described or notfithediseharge endof the passage K maygbe considered as a connection leading.

from a fuel. supply or carbureter to, a me 1 pchanically operated two-way cock or valve" fromwhich a passage R, controlled. by check valve R leads to'the work'ng chainof the cylinder K. Y The val eltcon- .nects the passage R. at certainftimes gwith V M, operated by aspring-returned push-pin M! the carbureter or fuelsupply passage' K,

and at other times with the atmosphere,]

through a connection R The mechanism for operating the valve is governed by the rotatlng parts, and 1n the particular embodiment shown is constructed as follows: A pinion R is rigidly secured to the cock'or valve R, and is. in,

mesh with a spring-pressed-rfack S, suitably guided in a stationary part, and plvotally connected with a lever T', fu'lcrumed at'T'.

The lever T carries an antifriction roller whichfis adapted to engage the three cams U or the three cams U, each set being arranged in a difi'erent plane, and each comprising as many cams as there are groups of undulations in the grooves of the disks C, C,'D. The lever T can be shifted into operative relation to either the cams U' or the camsU, by the following mechanism:

Said lever is carried loosely by. the pivot or fulcrum T which a spring T tends to keep inward against the disk (see Fig. 7), in operative relation to the cams U. To the fulcrum or pivot T is hinged at T an arm T longer than the inner portion of the pivot T (counting from the connection T and carrying'a roller T adapted to engage i the disk C and capable of a certain play owing to the provision ofslots T. The inner endof the arm T is at one side of the lever T, and has an extension T arranged at a right angle to the body'of the arm and carrying a roller T". A spring T tends to throw the arm into the position shown in Fig. 8. ,As long as the disk C rotates inthe;d'ir eitio n indicated in this figure, the arm T will be substantially parallel; with the, pivot T, the roller T engaging the disk C and keeping the lever T n operative'relation'to the set of cams U.

Should the direction of the disks rotation be reversed (as by intentionally effecting an early ignition) the arin'T- will assume the oblique position shown in Fig. 7, the roller T then riding on the disk C, and the 'lever'T being shifted inward to cotiperate with the set. of cams U. Similarly should the engine be reversed while the parts. are

'in' the position last referred to, the'changed motion of the'diskC willearry the arm T to the position shown infFig. 8, thus shifting the-lever T outward to again cooperate with the cams U. i y y The cams U, U are carried by the disk C and aremounted tofslider radiallyaih guides U Pin'sor other project ons U extend from the cam stems into a gr'odve V 'tpf a normally stationary disk or ringV; pro-" vided with guide pins workingin'vertical slots A of the end plate-A.

. The'difference in the length of the vag I rious piston strokes described above is ob tained by the peculiar formation ofthe guide grooves on the disks C,'O, 1D. The

short undulations c, 0' correspond to the short second and third strokes respectively,

hile the undulations a, a, I), Z), terminate at, a greater distance from the center, so as to give the proper effect to the other strokes of the piston. During the third stroke (working stroke), the piston I through the medium of the reciprocating member H,

drives the disks C, C", D and the shaft 3.;

The momentum of the parts carries them during the other strokes of the piston," and the undulations a, a, I), b and 0 govern the length and position of the piston stroke as described. v

in opposite directions on the disk D and on I the disks C, (l', and are, as it were, at cross .ing points of the guide grooves of said. disks ver TY or t, the engine will be braked o stopped very quickly, since the exhaust valve 51: .Would remain closed, or the valve Rwould remain closed to the passage K,jor both con-1 ditions might-be produced at the same time.

It will be seen that the projections H act the piston I and the reciprocating member H, although a. rigid connection might be substituted. To further guard against theeffect of shocks, the inner Walls of the guide portions 0, (corresponding to-the =Working stroke) may be of inelastic nature, as indicarted at e in Fig. 9, and when the engine Q is reversible, a similar constructlon e may be employed at the guide portions 0, sincethese cams U, U, Z, Z, or even only one 'set of them, will not engage the correspondinglethe yalve R or Y may be altered, for thepu r pose of varying the speed, or simply; to ad Various modifications may be made with respectively is opened may be regulated, to control'the speed of the engine.
